GAS HEATING AIPARATUS.

Specification of Letters latent.

Patented March 3,1908.

Application filed January 2S. 1907. Serial No. 354.407.

the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon?, which form a part of this specification. My present invention relates to a gas heati ing apparatus and more particularly to an section, and a part apparatus of that class furnaces. It is the object ofv my invention to provide a. gas heating apparatus which may be apj lied to any ordinaryA type of hot air furnace for heating purposes, but which when. so applied will not in any way interfere with the usual operation'of ythe furnace, it being possible with my apparatus to simultaneously heatl the furnace with both coal and gas. To accomplish these objects'I` have provided the improved details of structure which will presentlybe fully described and pointed out 1n the claims, reference being had to the ac.- companying drawings forming part of this specification, 'n which vlike lreference numerels refer to llike parts throughout the sevL eral views, and in whichf- A FigureI is 'a front elevationY of a furnace `ofthe ordinary type equip ed with my' gas heating apparatus, one of t e hoodsbeing in of the furnace jacket being broken away for better illustration. Fig. II is a view in s'ide elevation showing one of the hoods, whieh is partially broken away for better illustration.' Fig. III is van enlarged detail view ,of the burner and mixing chamber. Fig. IV is a bottom plan view of the mixing chamber.

Referring more in detail to the `parts,1 represents a furnace jacket, which is ordif narily constructed of sheet metal, and in-y closes a cast metal fire bowl 2, within which coal or like fuel is burned for heating purposes, there being a space between the bowl 2 and jacket `1 for the circulation of heated air, which air'is conducted through pi ojiiening` into the space between the jackes for use4 with hot air bottom;A the base of etl and bowl, and leading to the various apart ments in the building which it is desired to heat. v In thejacket I provide one or more out' out portions, indicated at 3, and over the cut out portions I secure a hood 4 which 1s secured at its upper and Aside edges to the furf nace jacket and slants outwardly toward the the hood being open to receive the burner 5, which comprisesv a tube extending substantially the 4length of the hood and is provided with a number of perforations 6, through which the. gas is 'discharged against an asbestos or like lining 7 on the' inner surface of hood' 4.

Burner 5 is supported on the up a mixing chamber 8, which may er end of e of any 'suitable type, and is provided with openings at its lower end, and with a slide 9 for closing and opening said openings to regulate the admission of air to the chamber. y The mixing chamber is supported on a feed pipe 10,

`having a valve 11 and connected with'a j source of supply,

not shown.

As before stated, the' furnace jacket may be provided with any desired number of cut out portions and hoods, the number depending on the size of the furnace and the amount ofheat which. it is desired to generate. -1

When the parts mentioned have been arranged as described, and the gas ignited, the fiame'from jugement with the asbestos lining to the liood, which assists in the combustion and increases the amount of heat which is carried into the space between the jacket fand fire bowl, and from thence into the pipes leading to the various apartments. The mixture of gas and air is secured in the manner mentioned, and the regulation ofthe flow of gas re lated in the ordinary'manner.

lith this apparatus it is not necessary to alter the fire bowl in which coal or like fuel is burned, and if desired there may be a fire in the bowl and an operation of the gas burner at thesame time, thereby obviating the necessity for a change in the furnace construction., should it be desired to change from the'use of coal to gas, as a fuel, or vice versa.

Having thus described the invention, what I claim as new therein and desire to secure by Letters Patent is l., The combination with a furnace having a jacketprovided. with a out out portion, of,

the burning gas lwill rise into ima hood projecting from said jacket and covering said cut out portion, and a burner located in said hood.

i 2. .The combination with a furnace having a jacket provided with a cutout portion, of a hood having close contact with saidy jacket at the top and sides of said cut out portion, but open at the bottom, and a burner located in said hood, for the purpose set forth.

3. The combination with a furnace having a jacket provided With` a Acut out portion, of a hood having closeacontact With said jacket at the top and sides of said cut out portion, but open at the bottom, a burner located in said hood near the bottom, and a mixing chamber and, feed pipe projecting into said open bottomand supporting said burner.

4. The combinatlon With a furnace having a jacket provided With a out out portion, of a Wedge shaped hood having a close contact with said jacket at the top and sides of said cut out portion and extending outwardly toward the bottom, and a burner located in said hood near the bottom, for the purpose set forth.

5. The combination with a furnace having a jacket provided With a cut out portion, 'of a hood carried by said jacket in communica tion with said cut out portion, an asbestos linin' in said hood, and a burner located in said ood, for the urposeset forth'.

In testimony whereof I afHX my signature in presence of two Witnesses.

THOMAS P. WATTS.
